Description

An integral rubber safety support body for tires

technical field

The invention relates to the field of traffic safety, in particular to an integral rubber safety support body for tires.

Background technique

A highway, referred to as a highway, refers to a highway specially designed for high-speed driving of vehicles. Expressways have different regulations in different countries, regions, eras, and academic fields of scientific research. According to China's "Technical Standards for Highway Engineering" (JTG B01-2014), expressways are multi-lane highways specially designed for vehicles to drive in different directions and lanes, and all control access. The annual average daily design traffic volume of the expressway should be more than 15,000 passenger cars, and the design speed should be 80 to 120 kilometers per hour.

Due to the speed of the car on the highway, the friction between the ground and the wheel does work, and the mechanical energy is converted into the internal energy of the tire, which increases the temperature of the tire and expands the gas in the tire, resulting in a puncture. When a tire bursts suddenly when the vehicle is driving at high speed, the steering wheel and direction of the vehicle will lose control, which is very dangerous.

In the existing tire structure, in order to ensure that the vehicle will not lose too much balance when the tire blows out, a layer of support structure is usually added to the tire, so that when the tire blows out, the support structure can quickly support the vehicle and avoid the loss of the vehicle. control resulting in casualties. However, the existing support structure cannot make the car continue to drive when the tire blows out, so that the driver cannot move the vehicle to the maintenance area, and can only passively wait for rescue. security cannot be adequately guaranteed.

SUMMARY OF THE INVENTION

In order to solve the above-mentioned technical problems, an integral type rubber safety support for tires is provided. This technical solution solves the problem of the existing tire structure proposed in the above-mentioned background technology. In order to ensure that the vehicle will not lose too much balance when a tire blows out, usually A layer of support structure is added to the car tire, so that when the car has a tire blowout, the support structure can quickly support the car, so as to avoid the loss of control of the car and cause casualties, but the existing support structure cannot make the car continue to drive when the tire blows , so that the driver cannot move the vehicle to the maintenance area, and can only passively wait for rescue, so that the safety of the driver and passengers cannot be fully guaranteed when the tire blows out, especially when the tire blows out in the wild.

In order to achieve the above purpose, the technical scheme adopted in the present invention is:

An integral rubber safety support body for tires includes a rubber support body, the rubber support body is sleeved on a wheel hub, a tire is sleeved on the wheel hub, a mounting ring is movably connected on one side of the wheel hub, and the wheel hub A fixing ring is slidably connected on the same side of the mounting block.

Preferably, the rubber support body is arranged inside the tire, and the bottom of the rubber support body is close to the nipple portion of the tire.

Preferably, the surface of the rubber support body is provided with a sensor layer, and the inside of the rubber support body is provided with a gas cavity.

Preferably, a gas control layer is provided on the inner surface of the gas chamber, and a gas generating layer is provided on the outer surface of the gas control layer.

Preferably, there is an interference fit between the rubber support body and the wheel hub.

Preferably, the rubber support body is made of rubber material with high elasticity and low heat generation formula.

The advantage of the present invention is that the tire with the rubber safety support provided by the present invention expands under the action of the internal pressure during normal running, without touching the support and affecting the normal running. In the event of a tire blowout, the support body acts quickly, so that the vehicle does not lose too much balance, the vehicle stops safely, avoids serious traffic accidents, and brings a certain guarantee to the safety of drivers and passengers. At the same time, the rubber support body also It can support the car for a certain distance, so that the driver and passengers can reach the maintenance area, which further ensures the safety of the driver and passenger. The control layer transmits a signal, and the control layer compares the signal with the original set start value. When the tire blows out, the controller layer sends a start signal to the gas generation layer according to the signal sent by the sensor layer, and the gas generation layer receives the start signal. When the reaction occurs rapidly, a large amount of gas is generated after cooling and filtering, and then it is transported into the gas cavity. The gas cavity expands under the action of the gas, and the rubber support body is pressed against the inner surface of the tire, so that the tire can still support the car for a certain distance. The structure of the present invention Simple, easy to install, good support effect, high safety factor, which greatly protects the personal safety of drivers and passengers.

Detailed ways

The following description serves to disclose the invention to enable those skilled in the art to practice the invention. The preferred embodiments described below are given by way of example only, and other obvious modifications will occur to those skilled in the art.

Please refer to FIG. 1 , an integral rubber safety support body for tires includes a rubber support body 3 , the rubber support body 3 is sleeved on the wheel hub 1 , and the rubber support body 3 is an interference fit with the wheel hub 1 . The tight fit enables the rubber support body 3 to be firmly installed on the hub 1, the wheel hub 1 is covered with the tire 2, the rubber support body 3 is arranged inside the tire 2, and the bottom of the rubber support body 3 is close to the mouth of the tire 2. One side of the wheel hub 1 is movably connected with a mounting ring 5, and the wheel hub 1 is slidably connected with a fixed ring 4 on the same side of the mounting ring 5. Through the unique structural design, the rubber support body 3 is easy to install.

Referring to FIG. 2 , a sensor layer 6 is provided on the surface of the rubber support body 3 , a gas cavity 301 is provided inside the rubber support body 3 , a control layer 7 is provided on the inner surface of the gas cavity 301 , and a gas generating layer 8 is provided on the outer surface of the control layer 7 , the rubber support body 3 is made of a rubber material with a high elasticity and low heat generation formula, and the rubber material with a high elasticity and low heat generation formula enables the rubber support body 3 to support the car for a longer distance.
